标题： Dirac theory from a field theoretic point of view

摘要： 量子场论中由于无限多的自由度而出现了一些复杂情况。然而，直到现在，单粒子效应和多粒子效应之间的区别——主要由真空引起的——还不清楚。为了探讨这些问题，发展了单粒子狄拉克理论的场论图像。重点放在将格拉斯曼代数注入在其上构建的内端子克利福德代数上。所得的“场论”泛函方程表现出非常不寻常的行为。给出了处理狄拉克和量子场论的新方法。 显示英文摘要

摘要： Several complications arise in quantum field theory because of the infinite many degrees of freedom. However, the distinction between one-particle and many-particle effects -- mainly induced by the vacuum -- is not clear up to now. A field theoretic picture of the one-particle Dirac theory is developed in order to explore such questions. Main emphasis is laid on the injection of Grassmann's algebra into the endomorphism Clifford algebra built over it. The obtained ``field theoretic'' functional equation behaves in a very unusual way. New methods to handle Dirac and QFT are given.
